WELCOME TO MY WEBSITE!



I am a senior economist at the Belgian Competition Authority (Chief Economist Team). My work involves both casework and longer-term projects. The former primarily focuses on merger reviews and abuse of dominance investigations, where I provide economic expertise to support case handlers. I combine both theoretical models and empirical methods to assess competition dynamics and identify theories of harm. I also actively contribute to sectoral studies and the development of new instruments. These include, among other things, merger screening tools, local market analysis methods, and simulation techniques.

I hold a PhD in Economics from the Université Libre de Bruxelles, an MRes in Economics from the Institut Polytechnique de Paris, and an Engineering degree in Statistics from ENSAE Paris. You can find more details about my background and current activities in my resume
